One of my clients that has a donut shop/restaurant gives LEO's meals at a discount. When the come in for lunch or whenever, they get what they want full meal, and I think he charges them a flat 2 bucks. BTW there is usually one or two patrol cars in the lot pretty much every day. That is the owners descision to do it.
When he opened a second location right across the street from the PD/Courthouse etc, he was not able to extend the same policy at that location. It would have closed quicker than it did.
On a funny note to this. One day when at the counter, a local Housing Authority Security person (no gun or badge, just a decaled shirt) came in made his full order and pulled out 2 bucks. The gal behind the counter said that will be 5 dollars and some change, the guy looked puzzled, and said I thought security got it for 2 bucks. She said, ah, no that would be for LEO's, well apparently the guy only had 2 bucks, but I haven't seen him back at the place.
Apparently word had gotten around about the LEO discount, but somewhere it must have gotten messed up when passed down the line.
